LREM key count value

自1.0.0起可用。

时间严重年夜度:华夏棋牌 O(N)其中N是列表的长度。

从存储在列表中count的元素中删除第一次泛起的元素。这个论点以以下要领影响着操作:valuekeycount

  • count > 0:删除相当于value重新到尾移动的元素。

  • count < 0:删除即是value从尾部移动到头部的元素。

  • count = 0:删除一切即是的元素value

例如,LREM list -2 "hello"将删除"hello"存储在列表中的最后两个婚配项list

请重视,不存在的键被视为空列表,以是当key不存在时,该敕令将一直前往0

前往值

整数回复:删除的元素数目。

例子

redis>  RPUSH mylist "hello" (integer) 1 

redis>  RPUSH mylist "hello" (integer) 2 

redis>  RPUSH mylist "foo" (integer) 3 

redis>  RPUSH mylist "hello" (integer) 4 

redis>  LREM mylist -2 "hello" (integer) 2 

redis>  LRANGE mylist 0 -1 1) "hello" 2) "foo"
